The brush scuttle looks like a great idea. Right now I fill up the scuttle with hot water...both the lower and upper sections. I put my brush in the hot water while I shower and let the scuttle get nice and warm. After the shower I dump out the water and refill the lower section with hot water and start making lather. The dribble port is a small hole she puts in the upper lip of the scuttle. It allows you to tilt the scuttle and get a trickle of hot water into the bowl to help make lather.
